A vehicular autonomous driving system includes a time division multiplexed (TDM) bus, an autonomous driving (AD) controller coupled to the TDM bus, and a plurality of AD sensors coupled to the TDM bus. The AD sensors are configured to collect AD data and transmit collected AD data to the AD controller on the TDM bus in an assigned time slot at a first power level. A first AD sensor of the plurality of AD sensors is configured to, based upon collected AD data, detect an AD emergency event. In response to the detection, the first AD sensor is configured to transmit an AD emergency message on the TDM bus in a non-assigned time slot and at a second power level that exceeds the first power level. The AD sensor may transmit the AD emergency message in a particular sub-slot of the non-assigned time slot.

A multiplexer includes filters connected to each other at a common terminal, a low-frequency filter with a first pass band, and a high-frequency filter with a second pass band that is higher than the first pass band. The low-frequency filter includes an initial-stage filter section including at least one first elastic wave resonator located on the common terminal side among at least two elastic wave resonators, and a subsequent-stage filter section that includes a second elastic wave resonator other than the at least one first elastic wave resonator. A reflection coefficient in the second pass band when the initial-stage filter section is viewed from the common terminal side as a single component is larger than a reflection coefficient in the second pass band when the subsequent-stage filter section is viewed from the common terminal side as a single component.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for communication time slot allocation in a communication network. In one aspect, a first network device may determine that a second network device will transmit one or more packets associated with a first latency, and determine that a third network device will transmit one or more packets associated with a second latency. The first network device may determine to allocate a greater quantity of communication time slots to the second network device than to the third network device based, at least in part, on the first latency being less than the second latency. The first network device may allocate a first plurality of communication time slots of a beacon period to the second network device, and allocate a second plurality of communication time slots of the beacon period to the third network device.

A system and method for providing communications between a hub (medical controller) and a node (an implant) are disclosed. The hub selects an operating channel within a channel group in accordance with applicable regulations, and transmits signals to facilitate communications with nodes. A node sequentially tunes to individual channels within the group, monitoring each channel for a hub transmission during a monitoring period. If a hub transmission is detected, the node stays on the current channel. Otherwise, the node tunes to a next channel in the channel group. The hub transmission may be directed to unconnected nodes, to a single connected node, or to a group of connected nodes. The node transmits a first frame to the hub at a designated transmission time and receives a response. The node reports an emergency by sequentially transmitting emergency frames on each of the channels until receiving an acknowledgment from the hub.

A network device provides output data rate control having variable bandwidth and a response time constant that increases according to an amount of time that an input rate of data to the network device is evaluated by the logic to provide output data rate control. The device applies a rate estimate when a determination of the output rate to a predetermined accuracy is unavailable.

A process of scheduling stream packets for output from a multiplexing network device involves prioritizing the output of packets first according to stream priority, and within a particular priority, by stream ID.

Methods and apparatus for providing one or more services such as video on-demand, switched digital video, or Internet services using shared bandwidth. Exemplary embodiments include methods and apparatus for providing video on-demand and switched digital video to a set of customer premise equipment devices using a first dedicated portion of the bandwidth to provide video on-demand services, a second dedicated portion of the bandwidth to provide switched digital video services, and a third portion of the bandwidth to provide both switched digital video and video on-demand services wherein the size of the bandwidth made available to provide video on-demand within the third shared portion of bandwidth varies as a function of requests for video on-demand and switched digital video services and the priorities of the new requests versus the existing operating services. Bandwidth management occurring in accordance with bandwidth sharing policies, priorities and rules generated by a bandwidth sharing mechanism.

Disclosed is a method for allowing a terminal to transmit and receive signals to and/from a base station in a wireless communication system using a time division multiplexing method. Specifically, the method comprises the steps of: receiving a request signal for resetting into a second uplink/downlink setting while transmitting and receiving a signal according to a first uplink/downlink setting; terminating an uplink retransmission process associated with a specific uplink subframe when the use of the specific uplink subframe is changed into a downlink subframe according to the second uplink/downlink setting; and applying the second uplink/downlink setting at a specific time point to transmit and receive signals.
